spots peculiar to Acraea pupae are much reduced. The pupal 

 stage lasted fifteen days in January." 



Triinen says the young larvae feed in companies and 

 drop to the ground on a silken thread when alarmed. 



Tlie species is undoubtedly closely allied to A. cepheus 

 of the west.

^. Expanse 46-50 mm. F.-w. somewhat elongated. Bright 

 red with a blackish apical patcli 4-6 mm. wide, more or less 

 continued as a narrow blackish marginal border. A little black 

 at base and black spots as follows :— One in cell at or beyond 

 origin of nervule 2, one on end of cell, a discal band of five spots, 

 the first small in 10, the second larger in 6 and rather more 

 distal, the third below it in 5, the fourth in 4, more distal and 

 with its long axis pointing downsvaids and oatwai'ds, the fifth 

 below it in 3 but with its long axis pointing dowmvards and 

 inwards. A large spot near base of 2 and beneath it but nearer 

 margin a spot in Hi. Sometimes a subbasal spot in same area. 



H.-w. bright red with some black at base especially in Ic. 

 A narrow black hind-marginal border with a somewhat

 in 5 ; one near base of area 4 and beneath it but much nearer 

 margin a spot in 3, one near base of area 2 and immediately 

 beneath it a spot in Ic, followed by one in lb slightly nearer 

 base. A subbasal in 7, two in cell, and one on discocellular at
